  1. OMG Issue

UML14 — Profile Notation

  • Key: UML14-55
  • Legacy Issue Number: 4219
  • Status: closed  
  • Source: David Frankel Consulting ( David Frankel)
  • Summary:

    I raised this issue at the AB level. I didn't recommend holding up approval
    of UML 1.4 over this but we agreed that the new RTF would take this matter
    up with dispatch.

    Pages 3-59 to 3-63 (Section 3.35): The new notation for defining Stereotypes
    and TaggedValues (i.e. for defining a Virtual Metamodel or "VMM") raises an
    issue. I can speak to this as a practical matter based on the profiling
    work I've done. When I define a Stereotype on a UML metamodel element, as
    in figure 3-32 on p. 3-61, I would like to reuse the official OMG definition
    of the UML metamodel element. I don't want to have to define it again
    before defining the relationship between my new Stereotype and that UML
    metamodel element. Thus, requiring the <<metaclass>> Stereotype on the UML
    metamodel element means that, in the UML metamodel itself, I would have to
    Stereotype all the metaclasses this way so that, if I need to, I can reuse
    them in VMMs. True, I could opt not to display the <<metaclass>>
    Stereotype in a pure UML metamodel diagram and opt to display it a VMM
    diagram, but all the UML metamodel elements would be carrying the
    <<metaclass>> Stereotype.

    The best solution I can think of to this problem is to to drop the
    requirement to use the <<metaclass>> Stereotype in VMM diagrams. As long as
    the requirement to use the <<stereotype>> Stereotype on Stereotypes (sic!)
    is adhered to, it should be pretty clear in a VMM diagram what is a
    Stereotype and what is a UML metamodel element. Also, the the standard
    metamodel Stereotype of Package indicates that the elements in the
    Package are elements of a metamodel.

    I am open to other suggestions as to how to resolve this issue.
